A primitive class can override `toString` implementation for their custom string representation.
This reminds me [JDK-8201462](https://bugs.openjdk.java.net/browse/JDK-8201462).
FWIW the current implementation already adds the randomness to
the hash code computation with a constant random 32-bit “salt”
configured at startup but it still carries the `31*x+` pattern which
should be cleaned up.
